1. Common Core #12 Part 2
Tell me everything you know about the graph:

2. ANSWER(S)
You could verbally express what is happening to the y-values as x increases, make a table based on the points plotted, write an equation to go with it. The equation of this line is y = -2x + 5

3. Common Core #12
Compare properties of two functions, each represented in a different way:
(1) verbally (2) table (3) equation (4) graph

4. Using Graphs to Make a Table and Write an Equation
Use the graph to make a table and to write an equation. y
Make a Table First x y x

5. Using Graphs to Make a Table and Write an Equation
Use the graph to make a table and to write an equation. y
Make a Table First x y 2 1 4 6 3 8 x

6. Using Graphs to Make a Table and Write an Equation
Use the graph to make a table and to write an equation.
Each value of y is 2 times the value of x plus 2. 6 2 8 3 4 1 y x y
y = 2x + 2 x

7. Using Graphs to Make a Table and Write an Equation
Use the graph to make a table and to write an equation.

8. Using Graphs to Make a Table and Write an Equation
Use the graph to make a table and to write an equation. x y 6 -1 3 -2 -3
y = 3x + 5

9. You write a problem
Draw a line on the graph that will result in either a (1) fractional slope or (2) fractional y-intercept or both
We will work some on the coordinate grid on the next slide.
It is a 6 x 6 grid.
